Abstract
Intranasal vaccination using influenza vectors is a promising approach to developing vaccines against respiratory pathogens due to the activation of the mucosa-associated immune response. However, there is no clear evidence of a vector design that could be considered preferable. To find the optimal structure of an influenza vector with a modified NS genomic segment, we constructed four vector expressing identical transgene sequences inherited from the F protein of the respiratory syncytial virus (RSV). Two vectors were designed aiming at transgene accumulation in the cytosol. Another two were supplemented with an IgGκ signal peptide prior to the transgene for its extracellular delivery. Surprisingly, adding the IgGκ substantially enhanced the T-cell immune response to the CD8 epitope of the transgene. Moreover, this strategy allowed us to obtain a better protection of mice from the RSV challenge after a single intranasal immunization. Protection was achieved without antibodies, mediated by a balanced T-cell immune response including the formation of the RSV specific effector CD8+ IFNγ+/IL10+-producing cells and the accumulation of Treg cells preventing immunopathology in the lungs of infected mice. In addition to the presented method for optimizing the influenza vector, our results highlight the possibility of achieving protection against RSV through a respiratory-associated T-cell immune response alone.

Abstract
Antigenic and genetic characteristics of Russian RSV isolates are presented for the first time. Of the 69 strains isolated in St. Petersburg, 93% belonged to the RSV-A antigenic group. The antigenic variations in the F-protein RSV were analyzed using a panel from 6 monoclonal antibodies by the method of micro-cultural ELISA. Depending on the decrease in the effectiveness of interaction with monoclonal antibodies (relative to the reference strain Long), RSV-A isolates were divided into 4 antigenic subgroups. The results of 24 isolates sequencing showed that more than 60% of them had substitutions in significant F-protein sites compared to the ON67-1210A reference strain of the current RSV genotype ON1/GA2. The most variable were the signal peptide and antigenic site II. When comparing the results of ELISA and sequencing, it was not possible to identify any specific key substitutions in the amino acid sequence of the F-protein that affect the interaction of the virus with antibodies. The nucleotide sequence of the F-gene from 19 of the 24 characterized isolates was close to that of ON67-1210A reference virus and was significantly different from RSV-A Long and A2 viruses. A separate group consisted of 5 strains, in which the F-protein structure was approximated to RSV Long.

Abstract
Respiratory syncytial virus causes lower respiratory tract infections in infancy and old age, affecting also immunocompromised patients. The viral fusion protein is an important vaccine candidate eliciting antibody and cell-mediated immune responses. CD8(+) cytotoxic T lymphocytes (CTLs) are known to have a role in both lung pathology and viral clearance. In BALB/c mice, the fusion protein epitope F249-258 is presented to CTLs by the murine major histocompatibility complex (MHC) class I molecule K(d). In cells infected with recombinant vaccinia viruses encoding the fusion protein, F249-258 is presented by MHC class I molecules through pathways that are independent of the transporters associated with antigen processing (TAP). We have now found that F249-258 can be generated from non-infectious virus from an exogenous source. Antigen processing follows a lysosomal pathway that appears to require autophagy. As a practical consequence, inactivated virus suffices for in vivo priming of virus-specific CTLs.

Abstract
The transporter associated with antigen processing (TAP) translocates the viral proteolytic peptides generated by the proteasome and other proteases in the cytosol to the endoplasmic reticulum lumen. There, they complex with nascent human leukocyte antigen (HLA) class I molecules, which are subsequently recognized by the CD8(+) lymphocyte cellular response. However, individuals with nonfunctional TAP complexes or tumor or infected cells with blocked TAP molecules are able to present HLA class I ligands generated by TAP-independent processing pathways. Herein, using a TAP-independent polyclonal vaccinia virus-polyspecific CD8(+) T cell line, two conserved vaccinia-derived TAP-independent HLA-B*0702 epitopes were identified. The presentation of these epitopes in normal cells occurs via complex antigen-processing pathways involving the proteasome and/or different subsets of metalloproteinases (amino-, carboxy-, and endoproteases), which were blocked in infected cells with specific chemical inhibitors. These data support the hypothesis that the abundant cellular proteolytic systems contribute to the supply of peptides recognized by the antiviral cellular immune response, thereby facilitating immunosurveillance. These data may explain why TAP-deficient individuals live normal life spans without any increased susceptibility to viral infections.

Abstract
Defective ribosomal products (DRiPs) are a subset of rapidly degraded polypeptides that provide peptide ligands for major histocompatibility complex (MHC) class I molecules. Here, recent progress in understanding DRiP biogenesis is reviewed. These findings place DRiPs at the center of the MHC class I antigen processing pathway, linking immunosurveillance of viruses and tumors to mechanisms of specialized translation and cellular compartmentalization. DRiPs enable the immune system to rapidly detect alterations in cellular gene expression with great sensitivity.

Abstract
The transporters associated with antigen processing (TAP) allow the supply of peptides derived from the cytosol to translocate to the endoplasmic reticulum, where they complex with nascent human leukocyte antigen (HLA) class I molecules. However, infected and tumor cells with TAP molecules blocked or individuals with nonfunctional TAP complexes are able to present HLA class I ligands generated by TAP-independent processing pathways. These peptides are detected by the CD8(+) lymphocyte cellular response. Here, the generation of the overall peptide repertoire associated with four different HLA class I molecules in TAP-deficient cells was studied. Using different protease inhibitors, four different proteolytic specificities were identified. These data demonstrate the different allele-dependent complex processing pathways involved in the generation of the HLA class I peptide repertoire in TAP-deficient cells.

Abstract
CD8(+) T lymphocytes screen the surface of all cells in the body to detect pathogen infection or oncogenic transformation. They recognize peptides derived from cellular proteins displayed at the plasma membrane by major histocompatibility complex (MHC) class I molecules. Peptides are mostly by-products of cytosolic proteolytic enzymes. Peptidic ligands of MHC class I molecules are also generated in the secretory and vesicular pathways. Features of protein substrates, of proteases and of available MHC class I molecules for loading peptides in these compartments shape a singular collection of ligands that also contain different, longer, and lower affinity peptides than ligands produced in the cytosol. Especially in individuals who lack the transporters associated with antigen processing, TAP, and in infected and tumor cells where TAP is blocked, which thus have no supply of peptides derived from the cytosol, MHC class I ligands generated in the secretory and vesicular pathways contribute to shaping the CD8(+) T lymphocyte response.

Abstract
The history of vaccines for respiratory syncytial virus (RSV) illustrates the complex immunity and immunopathology to this ubiquitous virus, starting from the failed formalin-inactivated vaccine trials performed in the 1960s. An attractive alternative to traditional live or killed virus vaccines is a defined vaccine composed of discrete antigenic epitopes for which immunological activities have been characterized as comprehensively as possible. Here we present cumulative data on murine and human CD4, CD8 and neutralization epitopes identified in RSV proteins along with information regarding their associated immune responses and host-dependent variability. Identification and characterization of RSV epitopes is a rapidly expanding topic of research with potential contributions to the tailored design of improved safe and effective vaccines.

Abstract
The defective ribosomal product (DRiP) hypothesis of endogenous Ag processing posits that rapidly degraded forms of nascent proteins are a major source of peptide ligands for MHC class I molecules. Although there is broad experimental support for the DRiP hypothesis, careful kinetic analysis of the generation of defined peptide class I complexes has been limited to studies of recombinant vaccinia viruses expressing genes derived from other organisms. In this study, we show that insertion of the SIINFEKL peptide into the stalk of influenza A virus neuraminidase (NA) does not detectably modify NA folding, degradation, transport, or sp. act. when expressed in its natural context of influenza A virus infection. Using the 25-D1.16 mAb specific for K(b)-SIINFEKL to precisely quantitate cell surface complexes by flow cytometry, we demonstrate that SIINFEKL is generated in complete lockstep with initiation and abrogation of NA biosynthesis in both L-K(b) fibroblast cells and DC2.4 dendritic/monocyte cells. SIINFEKL presentation requires active proteasomes and TAP, consistent with its generation from a cytosolic DRiP pool. From the difference in the shutoff kinetics of K(b)-SIINFEKL complex expression following protein synthesis versus proteasome inhibition, we estimate that the t(1/2) of the biosynthetic source of NA peptide is approximately 5 min. These observations extend the relevance of the DRiP hypothesis to viral proteins generated in their natural context.
